Ray tracing is an image synthesis technique which allows the simulation of complex optic effects like refraction and reflection. Unfortunately this algorithm remains very expensive in computation. In order to minimize the processing times we propose an optimisation based on an adaptative décomposition of the working space and the rationalization of the optimization techniques. An analysis of the content and the localization of the information allow a selective application of the ray tracing. The method consists in an analysis of the position and of the repartition of the objects in order to determine the intersection possibilities. An recursive and adaptative decomposition, directed by a study of the content, reduces localy the complexity...
